To all whom it may concern:

Be it known that I, JOHN R. WINKLE, a citizen of the United States, and a resident of Swissvale, in the county of Allegheny and State of Pennsylvania, have made a new andv useful Invention in Jointed Rotary Valves, of which the following is a specifica tionr w, o

This invention relates to valves for intcrnal combustion engines and has for an chjectto produce an improved rotary valve which eliminates the dificulties encountered with valves of that type when employed in connection with multi-cylinder internal (30111 bustion engines.

A further object is to produce an articulate valve having. improved means for securing the separate sections of the valve together. These and other objects I attain by means of a valve, embodying the features herein described and illustrated in the dran ings accompanying and forming a part of this application.

In the drawings, Figure 1 is a l0ngitudinal section of a valve casin shown in connection with a valve embo ying my inven tion. Forconvenience of illustration 'porr tlons' of the valve are shown as if broken away.

Figs. 2 and 3 areperspective views of coupling members which form details of the valve illustrated as an embodiment of my invention.

most impossible, to so construct the bearings for a long cylindrical rotary valve that they will maintain an exact. alinernent during the Even Where the cylinders of the engine and the valve casing are cast on Z2200 and all of the bearings for the valve are bored in one continuous o eration, inequalities in the alinement o the bearings will. result either from a lack of exactness in the boring operation or from variations in temperature strains in the metal of the different cylinders. Where the diflicnlties resulting from a lnisalinenient of the bearings are aggravated by inaccuracies in shape of the valve itself the sticking of the valve is apt to render it inoperative or at least'to prove highly objectionable and to finally result in damage to the valve itself or to the valve casing. One of the principal objects of my present invention istopra duce an improved articulate valve which will overcome the difliculties above ennme'r-L ated and which will not of itself give rise to other diflieulties.

The valve illustrated is made up of tuloular sections 5 so arranged that when assembled they form a long tubular or cylindrical valve which is capable of rotating in a-eontinuous bearing having a plurality of hearing surfaces (5, formed within the valve casing 7. The valve casing is'shown as pro vided with ports 8-45, and bearing surfaces 6 are located between each set of. ports. Each section 5 is preferably of such lengththat it bridges at least one set of the ports 8 and engages bearing surface on each side.

of the ports. As shown each valve section. is provided with grooves or recesses 9 formed in its peripheral-face which alternately establishes communication between one engine cylinder and the admission and exhaust ports formed in the valve casing. This however forms no part of the present invention, which relates primarily to connecting the separate sections 5 together to form an organized valve. Each section 5- is provided at one end with a coupling member 11, so\

constructed that; it cooperates with a. con-a ,not engage relatively pling ring 12 in locking the section, upon which it is mounted to the next adjacent section. Each coupling member 11 is adapted to be set into one end of one of the sections 5 and is provided with a pair of lugs 12-3 which are adapted to engage cooperating lugs 14: formed on the cooperating coupling disk or ring 12. I

llach coupling member is formed in two diameters, and the external diameter of the smaller portion is such that the smaller portion may be inserted into the interior of the. tubular section 5. The receiving end of the tubular section is counterborcd to receive the portion of larger diameter of the coupling member and the counterborcd portion is of such depth that it produces an annular cxtension or flange 15 which, when the mem ber 11 is in place, overhangs it by an amount equal to substantially half the width of the ring 12. The member 11 maybe secured to the section by any suitable means such as for example, pins 16.

In assembling the valve the adjacent ends of the different sections are each provided with a coupling member 11 and the rings 12 are located between the coupling membcrs so that they look the adjacent sections against relative rotary motion but permit axial annular motion. The overhanging flanges 15 of the adjacent sections cooperate to incase the ring 12 and consequently produce a substantially unbroken bearing face for the valve. One of the advantages of this construction is that the ring 12 does rotating faces and there is nothing onthe surface of the assembled valve to cut or groove the bearing faces of the valve casing.

In the illustrated embodiment of my inshown a valve formed of two vention I have end sections 5 and one intermediate section 5. The intermediate section is provided with a, coupling member at each end while each othe end sections is provided With one coupling member only. Any suitable means may be emploved for holding the valve in place within t e casing but as illustrated I have provided at one end a stationary abutment 17 and at the other end an adjustable thrust bearing 18 screwed into the ca sing and adapted to engage a shoulder formed on the valve. As illustrated the valve is provided with a rotating gear19 and is adapted to receive cooling: liquid at one end from a port 20 formed in the casing and to deliver it from the other end.

In accordance -with the patent statutes I have illustrated and described vhat I now believe to be the preferred G-IJlbOdllllOIll; of my invention, but I desire it to be understood that various having past the member United States changes, modifications, substitutions, additions and omissions may be made in the structure illustrated Without departing from the spirit and scope of my invention.

1. An articulate valve comprising at least two sections, each section having longitudinally projecting annular flanges formed on the end adjacent to the adjacent section, and a coupling ring shaped member located be tween adjacent sections of the valve and surrounded by said annular flanges.

2. An articular valve, comprising hollow cylindrical sections, ea h section having a projecting flange on the end adjacent to the next section, and a coupling ring for coupling adjacent section's surrounded by the projecting flanges of the sections coupled and forming with the sections a continuous passage through the valve.

3. A rotary valve comprising separate cylindrical. sections, each section having a longitudinally projecting flange formed on one end thereof, and a coupling ring located between adjacent sections for positively locking said sections against relative rotary motion but for permitting said sections to rotate with their axes out of alinement, said coupling ring being surrounded by the projecting flanges of the coupled sections.

4. A rotary valve comprising separate sections, each section having a projecting flange and axially projecting lugs at one end thereof, said lugs being surrounded by said flange, and a coupling located between adjacent sections, surrounded by the flanges thereof and having axially projecting lugs formed on opposite'sides thereof for engaging the lugs of the coupled sections.
